LBTEK 0.5-inch Low-Deformation Stainless Steel Mirror Mount is used for mounting Optical Components with a Diameter of 12.7 mm, with 2 M4×0.2 Precision Adjusters without Knurled Knobs and with locking nuts. A three-point fixation using a Retaining Ring + wave washer secures the Optical Components; purchasing the mount includes 1 Stainless Steel Retaining Ring + 1 wave washer, compatible with Optical Components up to 6.4 mm thick. The 2 M4×0.2 Precision Adjusters without Knurled Knobs allow adjustment of the Pitch and Yaw of the Optical Components via a Hex Key. The optical mount has an M4 countersunk mounting hole on the side; purchasing the LBTEK Stainless Steel Mirror Mount includes hex socket ultra-low-head screws and a Hex Key.

Installation instructions: After inserting the Optical Components, insert the wave washer, making sure that the contact points between the washer and the back of the lens align with the positions of the three raised bosses on the mount. Insert the Retaining Ring and turn it until the Retaining Ring lightly contacts the back of the Optical Components, then back off the Retaining Ring by 90° (1/4 turn). This ensures that the wave washer provides elastic force to secure the Optical Components, ultimately ensuring that the surface figure of the Optical Components in the mount is below 0.1λ.
Note: These mounts are used to mount 12.7 mm Optical Components with a tolerance of +0/-0.13 mm. For low surface figure applications, one nylon-tipped screw on the three-point raised bosses must be fully loosened and must not contact the Optical Components. For applications without low surface figure requirements, a torque wrench can be used to tighten the Optical Components at a torque of 2cN.m to provide longer-term Stability.
